본 고안은 예를 들면 전자 레인지의 고주파 발진회로에서 고압 변압기로 사용되는 변압기에 관한다.The present invention relates to a transformer used as a high voltage transformer in a high frequency oscillation circuit of a microwave oven, for example.

일반적으로 이와 같은 종류의 변압기로는 제1도 및 제2도에 도시하는 것이 있다. 제1도 및 제2도에서 (1)은 E형 라미네이트 철심이고 E형의 라미네이트를 다수매 적층하여 구성된다. 이 철심(1)의 중앙자각(磁殼)(1a)에는 1차코일(2) 및 2차코일(3)이 장착된다. 이 경우에 코일(2),(3)의 장착에 있어서는 그 양코일 상호간에 일정 거리를 확보하기 위하여 스페이서(도시 생략)가 장착된다. 또 코일(2), (3)에는 철심과 충분한 절연상태를 확보하기 위하여 제3도의 도시와 같은 절연지(4)를 각각 감는 동시에 리이드선 접속용의 단자판(5)이 각각 장착된다. 이와 같이 철심(1)의 각 자각의 단면에는 I형 라미네이트 철심(6)이 용접되고, 이것에 의하여 EI형 라미네이트 철심이 구성된다. 이 EI형 라미네이트 철심은 기대(7)에 장착된다. 또 철심(6)은 I형(구형)의 라미네이트를 다수매 적층한 것이다.Generally, transformers of this kind are shown in FIGS. 1 and 2. (1) in FIG. 1 and FIG. 2 is E type laminated iron core, Comprising: It laminates | stacks multiple sheets of E type laminate. The primary coil 2 and the secondary coil 3 are attached to the central shell 1a of the iron core 1. In this case, in mounting the coils 2 and 3, spacers (not shown) are mounted in order to secure a certain distance between the coils. The coils 2 and 3 are respectively wound with an insulating paper 4 as shown in FIG. 3 in order to secure an iron core and a sufficient insulating state, and terminal plates 5 for connecting lead wires are respectively mounted. Thus, the I type laminated iron core 6 is welded to the cross section of each magnetic core of the iron core 1, and this constitutes an EI type laminated iron core. This EI type laminated iron core is attached to the base 7. The iron core 6 is obtained by laminating a large number of I-type (spherical) laminates.

그리고 자각(磁殼)(1a)과 코일(2)의 내측과의 간극에는 그 자각(1a)의 양측에 있어서 각각 스페이서인 쐐기(8)가 삽입된다. 또 자각(1a)과 코일(3)의 내측과의 간극에도 동일한 쐐기가 삽입된다. 즉 쐐기(8)의 삽입에 의하여 자각(1a)에 대한 코일(2) ,(3)의 장착위치의 편재를 방지하고, 자각(1a)과 코일(2),(3)과의 사이에 각각 적정한 절연 거리를 확보하는 동시에 자각(1a) 의 각 라미네이트의 적층 방향으로의 확개(擴開)를 방지하고, 동작시의 굉음(轟音)을 방지한다.In the gap between the magnetic shell 1a and the inner side of the coil 2, wedges 8, which are spacers, are inserted at both sides of the magnetic shell 1a. The same wedge is also inserted in the gap between the magnetic shell 1a and the inner side of the coil 3. That is, the insertion of the wedge 8 prevents the ubiquitous of the mounting position of the coils 2 and 3 with respect to the shell 1a, and between the shell 1a and the coils 2 and 3, respectively. An appropriate insulation distance is ensured, and expansion of each laminate of the magnetic shell 1a in the stacking direction is prevented, and noise during operation is prevented.

그러나 쐐기(8)의 삽입은 철심과 코일과의 조립이 완료된 후에 하는 것이고, 이로 인해 코일의 편재를 확실히 수정하는 것은 실제에 있어서는 곤란했다. 또 편재를 확실히 수정하는 것이 곤란하기 때문에 자각(1a)과 코일과의 간극이 큰 쪽에서는 아무리 쇄기(8)가 있어도 자각(1a)을 압압할 수가 없고, 자각(1a)의 각라미네이트가 확개되어 동작시에 굉음이 발생된다.However, the insertion of the wedge 8 is performed after the assembling of the iron core and the coil is completed. Therefore, it is difficult in practice to correct the ubiquitous of the coil. Moreover, since it is difficult to reliably correct ubiquitous, even if there is a wedge 8 in the one where the gap between the awareness 1a and a coil is large, the awareness 1a cannot be pressed and the angle laminate of the awareness 1a is expanded, The sound is generated during operation.

본 고안은 상기와 같은 사정을 고려하여 연구된 것으로 그 목적은 간단한 구성으로 철심의 자각과 코일과의 사이의 적정한 절연 거리를 확보할 수 있고, 또 자각의 각 라미네이트의 확개를 방지하여 굉음의 발생을 미연에 방지할 수가 있고 또 비용절감을 가능케하는 변압기를 제공하는 것이다.The present invention has been studied in consideration of the above circumstances, and its purpose is to ensure a proper insulation distance between the core of the core and the coil with a simple configuration, and to prevent the expansion of each laminate of the core, the generation of noise To provide a transformer that can prevent the cost and to reduce the cost.

본 고안은 코일에 감긴 절연지의 일부를 절곡하여 그것을 스페이서로서 사용한다. 이하 본 고안의 한 실시예에 대하여 도면을 참조하여 설명한다. 단 도면에서 제1도 내지 제3도와 동일 부분에는 동일 부호를 달아서 그 상세한 설명은 생략한다.The present invention bends a part of insulating paper wound on a coil and uses it as a spacer. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same parts as in FIGS. 1 to 3 are denoted by the same reference numerals, and detailed description thereof will be omitted.

제4도, 제5도, 제6도의 도시와 같이 절연지(4)의 중앙부를 절결할 때 설편(4a) ,(4b)을 남겨놓고 그 설편(4a),(4b)을 도시와 같이 절곡하므로써 각각 스페이서로서 사용하도록 하고 있다. 이 경우, 설편(4a),(4b)은 일단 둘로 접어서 다시 둘로 접음으로써 그 중첩 방향으로 탄력성을 가지도록 한다. 단, 탄력성이 얻어지는지의 여부는 절연지(4)의 지질에 의해서 변하기 때문에 가령 아이론 가공한 아라미드지(aramid)로 절연지(4)를 구성하고 충분한 탄력성을 얻도록 하고 있다.As shown in FIGS. 4, 5, and 6, when cutting the central portion of the insulating paper 4, the tongues 4a, 4b are left and the tongues 4a, 4b are bent as shown. It is intended to be used as a spacer. In this case, the tongue pieces 4a and 4b are once folded in two and then folded in two so as to have elasticity in the overlapping direction thereof. However, whether or not elasticity is obtained varies depending on the lipid of the insulating paper 4, so that the insulating paper 4 is formed of, for example, aramid paper processed with iron, so as to obtain sufficient elasticity.

따라서 코일(2),(3)을 자각(1a)에 장치할 때 절연지(4)의 설편(4a),(4b)을 절곡해서 코일(2),(3)과 자각(1a)과의 간극에 삽입하면 그 설편(4a),(4b)이 스페이서로서 작용하고, 자각(1a)에 대한 코일(2),(3)의 편재를 방지할 수 있고 따라서 자각(1a)과 코일(2),(3)과의 사이에 적정한 절연거리를 확보할 수가 있다. 또한 스페이서 (4a),(4b)의 탄력에 의하여 자각(1a)의 각 라미네이트가 축적 방향으로 압압되고 자각 (1a)의 각 라미네이트의 확개를 방지할 수 있고, 따라서 동작시에 굉음의 발생이 없다. 또, 스페이서(4a),(4b)의 세트는 조립시에 완료되므로 종래와 같이 쐐기를 삽입하는 일이 필요 없고 작업이 간편하다.Therefore, when installing the coils 2 and 3 in the shell 1a, the tongue pieces 4a and 4b of the insulating paper 4 are bent to form a gap between the coils 2 and 3 and the shell 1a. When inserted into the tongue, the tongue pieces 4a and 4b act as spacers, thereby preventing the ubiquity of the coils 2 and 3 with respect to the shell 1a, thus preventing the shell 1a and the coil 2, Proper insulation distance between (3) can be ensured. In addition, due to the elasticity of the spacers 4a and 4b, the laminates of the shell 1a are pressed in the accumulation direction and the expansion of the laminates of the shell 1a can be prevented, so that no noise is generated during operation. . Moreover, since the set of spacers 4a and 4b is completed at the time of assembly, it is not necessary to insert a wedge as in the prior art and the operation is easy.

이상의 설명과 같이 본 고안에 의하면 간단한 구성으로서 철심의 자각과 코일과의 사이의 적정한 절연거리를 확보할 수 있고, 또한 자각의 각 라미네이트의 확개를 방지하여 굉음의 발생을 미연에 방지할 수 있고 또 비용의 절감도 가능한 변압기를 제공할 수 있다.As described above, according to the present invention, it is possible to secure an appropriate insulation distance between the core of the core and the coil as a simple configuration, and to prevent the expansion of each laminate of the core, thereby preventing the occurrence of noise. A transformer can be provided that can also reduce costs.
